Pick something that has a civilian equivalent when you get out, nothing wrong with being a crew chief or a mechanic; but you don't see a whole lot of civilian howitzers, tanks and apaches running around, also apache crew chiefs are the only ones that don't fly so go lift if you still want aviation. Actually go uav, (15w I think) shits the way of the future.
Don't be in any rush and don't sign on the dotted line unless they give you the MOS you want.

Hotel wasn't bad, all of us asked to be moved over to the low rise and had two bed room apartments with a kitchen and a living room; also if you called the service provider, I can't remember who it was, they would hook up your Xbox or whatever to a hard line.

I carried a glock at work for a while and I own an xdm & xds; all of them are great weapons however I prefer my M&P over all of them, doesn't feel like a brick in your hand plenty accurate and reliable.

Well look the bright side is the army will be better off with out you, go suck a dick.... wait they wont kick you out for that anymore, just tell them you want to suck start a shotgun so we can get rid of you.

how about you dont cerakote the 1911 and spend that money on a good holster? I use a Cross Breed mini tuck and love it, its a little pricey ($70-ish) but no part of the pistol comes into contact with my skin during normal carry.

commo (computer wizardry) or 15 (aviation) series mechanic of some type; aviation support facilities hire mechanics regularly as technicians and they make pretty decent money, not to mention you can get your ATP and work on civilian aircraft.

I don't really think it works that way; if you use WTC, a national guard run school house, they let you walk on with just a set of orders. The guard uses WTC for air Assualt and pathfinder, we don't have our own airborne school.

You have 3 fac levels, this is off the top of my head so forgive me if I dick this up, fac1 is line unit guys and their mins are 96 hours a year, fac2 maintenance platoon pilots and battalion staff officers mins are 60 a year and then fac 3 which is usually brigade and other random odds and ends only have to fly on the sim. I never really flew much at drill, but it all depends on what kind of unit you're in.
